dynaudio confidence 5 , which amp is fit ?

I tried the Pass X250 with these and found the sound a bit too forward and it would turn hard at louder vols. I just purchased a pair of ML436 monos and find them to be a much better match. Not as dynamic as the Pass but much more organic and holistic sound. I don't have the room for the Pass x600 monos so I wonder if that would give the best of both sounds. Other folks have raved about the Bryston monos with the Con. 5's.
Assoc. equip: ML #360S/Ml#37, Pass X1, Syn.res. Res Ref speaker, AQ Diamond XLR inter.

The Audio Research REF600MkIII monoblocks sound very good on the Dynaudios. It may be a little difficult digging up the spare $40k that they cost though.

Just don't get involved too much with the numbers.Gryphon and LAMM watts are quite different,try them both.
